But basketball isn't the only area where Duke students excel. From fighting against discrimination to sending time capsules into space to finding a quicker way to detect cancer, Duke students go above and beyond in all they do.

We tracked down 18 outstanding undergrads with help from the school's communications office and through recommendations from current students.

Class of 2015

Arun Karottu and Shelly Li started an electronic waste recycling company called Smart Metals Recycling after seeing how many electronics were thrown out at Duke at the end of each year. These electronics end up in landfills and harm the environment.

Smart Metals recycles old electronics by recovering reusable metals and plastics from devices and putting them back into the production cycle. The company handles over 100,000 pounds of electronic waste a day, and generates over $6 million in annual revenue.

Previously, Karottu, the vice president of sales, founded a medical device company that helps healthcare professionals perform certain tasks — like checking charts and accessing files — hands-free. Li, the president, is also a published sci-fi author.

When they graduate, the two seniors plan to build a refurbishing side to their operations and work on larger-scale projects, like decommissioning a power plant to find valuable parts to reuse and recycle.

Brittany Wenger developed cloud4cancer, a cloud-based artificial neural network that diagnoses breast cancer. Cloud4cancer uses a computer program that analyzes breast cancer diagnostic data to detect and recognize patterns in malignant tissue. The program is 99.1% sensitive to malignancy.

Wenger, who was named one of TIME magazine's 30 under 30, has presented her research to the Royal Society of Medicine and Clinton Global Initiative University.

While only a sophomore, Wenger plans on pursuing an MD/PhD when she graduates with the ultimate goal of becoming a pediatric oncologist.

Class of 2015

To Daniel Kort, certain insults are more than just hurtful words — they're an oppressive mindset. So he — along with Christie Lawrence, Jay Sullivan, and Anuj Chhabra — set out to change the thinking behind using these words, co-founding the "You Don't Say?" campaign in the process.

The photo campaign, which features student leaders and athletes, highlights the implications of words and phrases, such as "that's so gay" and "don't be a p---y," which can be marginalizing to particular identities. The campaign went viral, garnering over 20,000 followers on Facebook and landing features on several prominent news outlets, including The Washington Post, CNN, and ESPN.

Kort also works as a lab manager studying the social psychology of stereotypes, prejudice, and discrimination. He plans to purse a Ph.D. in social psychology and study the effects of homophobia and transphobia on the health and academic performance of LGBTQ individuals.

Class of 2015

At a school centered on basketball, David Helton has been a valuable asset in ramping up the football program. The linebacker received the 2014 William V. Campbell Trophy, often called "the academic Heisman," which goes to the player with the strongest academic success in the country, on top of his football performance and leadership skills.

In addition to the Campbell Trophy, Helton is also a four-time academic all-ACC football player, a 2014 academic All-American, and a Tatum Award recipient, which goes to the top scholar-athlete in the ACC.

Helton's dedication to his team stretches beyond the field as well. He founded and ran the Blair Holliday Fund, a nonprofit T-shirt company started in honor of a teammate who was hospitalized for a traumatic brain injury. He's raised nearly $50,000 through the fund.

Helton plans to enter the NFL draft at the end of April and work in business after his football career ends.

For Derek Rhodes, going to college in the same city where he grew up wasn't a deterrent, but an opportunity. As one of Duke's student body vice presidents, the Durham, North Carolina, native spent his two-year tenure focused on improving the relationship between Duke and the wider Durham community.

Rhodes revitalized the Duke-Durham Discount Program, which incentivizes students to explore local businesses in Durham through daily deals and discounts across the city. Rhodes also attends regular city council and neighborhood association meetings to discuss issues that affect students who live off campus.

Rhodes has also interned at both the US Department of Justice and The White House. Ever loyal to his hometown, Rhodes hopes to attend law school and run for mayor of Durham one day.

Class of 2015

Earlier this year, Gavin Ovsák presented "TEDxDuke 2015: Building Energy," a huge event attended by hundreds of students, faculty, and alumni, which took a team of 20 students six months to organize.

Ovsák became involved with TEDx when he presented a talk at TEDxYouthDay in high school. When he got to college, he grew the fledgling TEDxDuke from 100 attendees in 2013 to a sold-out auditorium of over 600 the next year. The event moved to an even larger space for 2015, and sold more than 500 tickets.

Ovsák also works closely with the Google Science Fair program, and will join Google's Knowledge Team as an intern this summer.

In the fall, Ovsák will head off to Harvard Medical School. He hopes to become a doctor and put his atypical background in computer science and engineering to use in future medical breakthroughs.

Class of 2016

As an athlete, Dumanyan struggled with the effects of pronation, which happens when the ankle bends inward too much or too little while running or walking and can lead to a host of injuries. This inspired her to develop SmartStrides, a wearable device that attaches to the heel and monitors the condition to prevent pronation-related injuries.

The idea grew into BioMetrix LLC, a company focused on creating specialized sensors for athletes. "The goal is to alert the user to imperfections in form, enabling them to stop an injury in its tracks," Dunanyan explains. "With virtually every athlete on the edge of injury, BioMetrix seeks to give the user more healthy days."

BioMetrix is currently developing a trial product, and plans to begin fundraising later this year. Though she's still in school, Dumanyan hopes to continue growing the company and learning more about coding technology.

Class of 2018

Jahlil Okafor is a force to be reckoned with on the court. Colleges begged him left and right to play for them while he was in high school, and now the 19-year-old center, who took his team to victory at the NCAA championship this year, announced that he'd be entering the 2015 NBA draft at the end of the year. He's only a freshman.

Okafor also knows how to play the tuba, and participated in musical theater and school plays before his college basketball career began.

Class of 2016

When a diving accident left Jay Ruckelshaus paralyzed, he decided not to let his disability stop him from experiencing everything Duke has to offer.

In 2013, Ruckelshaus founded Ramp Less Traveled, a nonprofit that offers financial aid and mentorship to students with spinal cord injuries. Last year, Ramp was featured in USA Today and made it possible for three students to attend college. Ruckelshaus also founded and directed "Beyond Disability, Beyond Compliance," the first-ever national conference on higher education and disability. Ruckelshaus hopes to help students with disabilities transition seamlessly into college life.

In addition to his work in disability advocacy, Ruckelshaus won first prize in a national political essay contest, earned the Angier B. Duke scholarship, and was elected to Phi Beta Kappa.

After graduation, he hopes to continue pursuing political theory, eventually going into policymaking.

In fall 2013, Justin Sandulli interned with the performing arts hub Lincoln Center, where he was involved in the planning and filming of two "Live from Lincoln Center" specials, which aired on PBS.

The first special was New York Philharmonic's opening night, which gave Sandulli the opportunity to assist backstage and stock Tony Award-winner Audra McDonald's dressing room. The second was the Richard Tucker Centennial Gala, a ceremony to award a star opera singer. Sandulli filmed interviews with a number of opera singers — footage that was used in the final gala broadcast.

Some of Sandulli's other endeavors include researching and writing New York City walking tour apps, and singing in the chorus for North Carolina Opera's production of "Aida" in front of an audience of about 2,000.

This summer, the Hawaii resident will return home to help curate an art gallery exhibit. He plans to make this the focus of his senior distinction project about Hawaiian art and architecture leading up to Hawaii's statehood.

Rence Nemeh produced "No to Dictatorship," a music video cover that advocates for freedom from dictatorial authority in the Middle East. The video made a splash, garnering over 180,000 collective YouTube views. Another video, "My Ferguson Makeup Tutorial," a serious yet humorous piece about race, was featured on Colorlines, an award-winning news site for advancing racial justice.

Nemeh also volunteers with refugees in Durham, and performs with Duke University Improv.

After graduation, Nemeh will join Chicago's prestigious Second City conservatory, where comedic greats like Tina Fey and Steve Carell got their start, to produce "a first-of-its-kind pop concert/sketch revue." He eventually hopes to work in the entertainment and/or political sphere to promote international peace and social justice.

Class of 2015

Sonora Williams experiments with mice deficient in serotonin, a chemical responsible for depression when there's not enough of it in the brain. Williams' study, which looks at the effects of a harmful early life environment on serotonin levels in mice, could someday be applied to humans and lead to more effective treatments for depression and a reduction in suicide among serotonin-deficient individuals.

Williams says her results have been promising so far, and expects to coauthor a few papers on her work.

Off-campus, Williams is training a therapy dog according to the American Kennel Club guidelines. She still has a way to go with her puppy, she says, but plans to get him registered as a certified therapy dog when he's older.

Williams has been accepted to medical school for the fall, and while she hasn't decided where she will go yet, she plans to specialize in pediatric neurosurgery.

Class of 2016

As a freshman, Zack Fowler joined the Women's Institute of Secondary Education and Research (WISER), a Kenya-based NGO that empowers girls through educational opportunities. Before WISER, no girl from the community had ever gone to college because the system made it too difficult for them to pass the entrance exam.

Fowler taught in local primary schools to help young women gain the skills necessary to enter the WISER program. Fowler helped more than 20 girls obtain college acceptances in the program's first graduating class, and the number of girls passing the exam increased by 250%.

Fowler has also obtained grants and funding for WISER; in addition, he works with Duke Splash, a community educational outreach program within the Durham, North Carolina, area.

Fowler still has one more year left at Duke, but is considering pursuing either a master's in public health or a Ph.D. in community research and action when he graduates.
